    i40e: Add support for getlink, setlink ndo ops · 51616018
    Neerav Parikh authored
    Add support for bridge offload ndo_ops getlink and setlink to
    enable bridge hardware mode as per the mode set via IFLA_BRIDGE_MODE.
    The support is only enabled in case of a PF VSI and not available for
    any other VSI type.
    
    By default the i40e driver inserts a bridge as part of the bring-up
    when a FDIR type VSI and/or a FCoE VSI is created. This bridge is
    created in VEB mode by default i.e. after creating the bridge using
    "Add VEB" AQ command the loopback for the PF's default VSI is enabled.
    
    The patch adds capability where all the VSIs created as downlink to
    the bridge inherits the loopback property and enables loopback only
    if the uplink bridge is operating in VEB mode.
    Hence, there is no need to explicitly enable loopback as part of
    allocating resources for SR-IOV VFs and call to do that has been
    removed.
    
    In case a user-request is made either via "bridge" utility or using
    the bridge netlink interface that requires to change the hardware
    bridge mode then that would require a PF reset and rebuild of the
    switch hierarchy.
    
    Also update the copyright year.
